▎ 摘  要

Cellulose-graphene oxide (GO) aerogel composites were successfully prepared from cellulose and GO dispersed in N-methyl morpholine-N-oxide monohydrate, a nontoxic and environmentally friendly solvent, after a freeze-drying process. Because of the strong interactions between the numerous oxygen-containing groups located on the surface of GO and the functional groups of the cellulose molecules, the GO monolayers were well dispersed in the three-dimensional porous structure of the cellulose aerogels. With the addition of 10 wt % GO, the swelling ratios and water contents of the composite cellulose-GO aerogels increased from 468 to 706% and from 82.4% to 87.6%, respectively. The corresponding maximum decomposition temperatures also increased from 335 to 353 degrees C with increasing GO content from 0 to 10%; this indicated that the thermal stability of the cellulose-GO aerogels was enhanced.
